There are a few other questions. Let's say config.py contains a variable
like 'font' that is a user set preference or a calibration value
calculated by A to keep with the thread title. Assuming both scripts are
running, how does the change get propagated to B after it is set in A and
written to the shared file? Is there a mechanism to allow both scripts to
make updates?
The easy way out is to assume the changes will be picked up when the
scripts are restarted but this is not always acceptable.
